Heart
Anatomy of a healthy heart.
Myocardial Infarction
commonly known as a heart attack, is the blockage of blood flow to part of the heart causing heart muscle death and scarring.
Cardiac Blood Flow
Cardiac blood flow to and from the body and the lungs.
Heart Blood Flow Regurgitation
Regurgitation is a disorder in which blood flows (leaks) backwards in the heart.
Vessel Balloon Before Inflated
Vessel Balloon Inflated with Stent
Creates a detour or "bypass" around the blocked coronary arteries of the heart.
Heart, major arteries and veins.
Contraction of artery wall muscles constricting blood flow to the heart.
Blood vessel constricted or stenosed by plaque.
Coronary artery blockage.
Coronary atherectomy removes plaque from the arteries supplying blood to the heart muscle. It uses a laser catheter, or a rotating shaver "burr" device on the end of a catheter.
A balloon is used to open narrowed or blocked blood vessels of the heart (coronary arteries).
A stent is a permanent device that is left in the artery to help the artery heal in an open position after an angioplasty.
Enlarged aorta leaving the heart, external and cross section views of an aortic aneurysm.
Schematic of blood through the heart, lungs and body.
Cardiac catheterization is when a thin plastic tube (catheter) into an artery or vein in the leg.
The balloon catheter is inflated to dilate stenotic valve leaflets to improve valve function and blood flow.
